A 60 GHz Broadband Wearable Antenna for Body-to-Body Communications
This paper presents a broadband antenna designed on flexible liquid crystal polymer (LCP) substrate for body-to-body short-range communications in 60 GHz frequency band. The antenna provides a wideband characteristic that covers the 51.1-70 GHz band centered at 60 GHz, owing to a coplanar waveguide (CPW) fed slotted patch structure. It attains a gain of 7.4 dBi and efficiency of 98% in the free space while 10.5 dBi and 67% in the on-body configuration. Through simulation and numerical analysis, paired antennas can cover at least 3.9-meter line-of-sight (LOS) body-to-body communications.
